Lost Girl's Anna Silk Pregnant with First Child

This is the first child for the 38-year-old Canadian actress with husband Seth Cooperman. The baby boy is due in May.

"I found out I was pregnant the day before we started shooting the last episode [of season three]," the expecting actress told Us Weekly. "It was very, very exciting and so hard to keep it a secret on set. I wanted to tell everyone at work, but I didn't...I talk about babies all the time, but when I got pregnant, I stopped saying anything about babies. I thought people were going to suspect something...It was really thrilling to finally be able to tell them though."

The mom-to-be later confirmed the news and expressed her happiness on Twitter.

"Thanks EVERYONE for the overwhelming congrats on my pregnancy news! We're so happy!!" she wrote.

The overjoyed father-to be is reportedly preparing for his impending fatherhood with the help of a book called "Dad's Pregnant Too".

"He's very excited. He's over the moon," Silk told Us Weekly. "Sometimes when I look over at him, he will be looking very emotional, and I'll say, 'What's wrong?' And he'll say, 'Your body is working so hard.' I'm really glad he has that book. He is already a great guy, but this makes him extra sensitive."

Silk, who experienced nausea and morning sickness during the first trimester, developed a liking for spicy food after conceiving her son.

"I could not tolerate it before, but I'm liking it now. I'm putting hot sauce on everything," she said. "My husband looks at me like, 'What are you doing?!'"

The couple, who wanted to have kids for a long time, has started calling their unborn baby Ninja.

"Publicly, we call him Ninja, because in his second ultrasound, he was doing all these crazy moves like a ninja," she explained to the magazine. "It's funny, because a lot of our friends refer to him like, 'How's Ninja?' It's cute. But that won't be his permanent name when he is born."

Silk, who first met actor Cooperman at an actor's workshop, reportedly got engaged in 2009 and later tied the knot.
